06 Colors

Colors in this library are strings containing the RGB hex values as in HTML colors. To make it more visible that a string is a color you should add an ‘#’ at the first position of the string but it is not necessary. The characters in the string can be uppercase or lower case.

$red = “#FF0000”;

TCPDF has a list of named colors (defined in the module tcpdf_colors.php) which you can use via the function getColorByName in the Report class. If you pass a valid color name, the function will return a color hex string that you can use for any function in the ReportLib that needs a color. If the name does not exist, the function will return a color string for black (i.e., “#000000”).

$color = ReportLib\Report::getColorByName(“gold”);

The example above returns “#ffd700”;
